Is there a difference between stock and broth?

When purchasing in the supermarket, the words are used interchangeably, but in culinary terms there is a difference. Both are the liquid strained from simmering meat, bones, vegetables and aromatics. The main difference is that stock is not a seasoned item. It’s destiny is a soup or sauce, to be seasoned during further cooking. Broth is a finished item. It is fully seasoned and intended to be eaten as such.
